The invention provides an industrialized full artificial reproduction method of Xu's flat scorpionfish; 1) industrialized broodstock selection and cultivation; 2) artificial insemination; 3) broodstock cultivation after insemination; 4) broodstock cloth pool and calving; 5) Seed breeding. The present invention establishes a factory-based fully artificial reproduction method for the scorpionfish, so that the success rate of broodstock insemination is over 88.5%, the survival rate of litter is over 78.6%, and the survival rate of seedlings is over 48.0%. Monthly cultivation can obtain high-quality fry with an average total length of 5.2cm, which effectively improves the reproductive efficiency of the female broodstock of Xu's flat scorpionfish, breaks through the large-scale mass production of its high-quality fry, and solves the problem of direct harvesting of broodstock with larvae to wild resources. It solves the problems of low mating rate in factories and low survival rate of litter, and has high promotion value. |
